Objectives: To learn how to protect the skin and to reduce the risk of photoaging and skin cancer
To learn differences between solar filters and formulations
To learn how to choose a sunscreen
To learn how to avoid common mistakes in the use of sunscreens by customers

Introduction: The incidence of skin tumors is increasing in all western countries. This phenomenon can be partly but not exclusively due to skin aging and a cultural and social behaviour leading to more sun exposures. However paradoxically this increase of incidence follows the increase of the sales of sunscreens pointing out that the wrong use of sunscreens may be more deleterious for the health than no use. In addition, some sunscreens have a poor quality and customers can not be readily identify good and bad suncreens.

Materials / method: We will clarify differences of the molecular structures of sunscreens, their mode of action, and efficacy in in vitro and in vivo conditions
We will explain the importance of the notions of SPF, UVA-PF, water resistance, stability and formulation and the common mistakes that customers and doctors do when they deal with their values and indexes.

Results: Practical suggestions will be provided.

Conclusion: A sunscreen can save the skin but, like all drugs, only if it is used properly. A bad use or bad products can be dangerous because they provide for a wrong feeling of being protected and they encourage to stay longer under the sun

Objectives: Expose different methods of photodynamic therapy practice to treat photoaging.

Introduction: Photodynamic therapy (PDT) is an effective method to treat photoaging.

Materials / method: PDT allows both a medical action by destroying dysplastic and tumor cells, and an aesthetic action by restoring skin density and texture.

Results: We will see multiple ways to practice PDT: laser pre-treatment, conventional PDT, Day Light PDT, Light Emitting Fabrics, PDT with Artifical White Light, use of fluorometry as well as different photosensitizers that can optimize results depending on the objectives and the topography.

Conclusion: There are now other techniques besides conventional PDT to treat photoaging. As a result, the new PDT treatment methods are now well tolerated and virtually painless. The therapeutic consequences are generally simple and without risk of scarring.
